But this page ought to help:
http://java.sun.com/webservices/docs/1.0/tutorial/doc/JSTL4.html
There is also a blurb about using the EL in the Struts FAQ entry on indexed properties.
If you look in your Struts distribution, you'll see the EL-related stuff in the contrib directory. You use the Struts EL tags the same way as you use the regular Struts tags (except you use the EL instead of using the old-fashioned runtime expression language).
For example:
<bean-el:size collection="${someBean.someCollection}" id="numItems"/>This Struts tag assumes there is a bean called "someBean" which exposes a collection via the no-arg method "getSomeCollection". It makes the size of the collection available via the "numItems" variable, which can be used subsequently like this, for example:
<c:when test="${numItems > 0}"/>There may be more efficient ways to do the same thing, but this gives you an example of a Struts tag and a JSTL tag that each use the EL.
I recommend the book "JSTL" by Sue Spielman (Morgan Kaufmann, 0-12-656755-7). It's only $20 new and worth it. It discusses the JSTL tags and the EL in depth and is based on example. I have found that using a combination of the Struts tags and JSTL tags made my JSPs the nicest, but I think there's not much the Struts tags do that the JSTL tags can't do.
Hope that helps,
Erik

Hi all,
I have following scenario.. I have FormBean which has getter and setter for my VO object
In VO I have a list of another VO.
Now on this form I want to display the contents of the list using logic.iterate tags.
I will make matter simpler saying...
aFormBean has aVO which as list of bVO. bVO has attributes like xAttr, yAttr, zAttr.
now aForm should show on the page table where contents of list of bVO
will be giving one one row of the table.
You can do this with struts logic and bean:write,I'm used to JSTL so here it is...
<c:forEach items="${yourFormName.aVo.bVOlist}" var="bVOitem"> <c:out value='${bVOitem.xAttr}'/> <%-- or JSP2.0 just ${bVOitem.xAttr} --%> <c:out value='${bVOitem.yAttr}'/> </c:forEach>
with logic iterate within your <html:form> tags (I 'think' this is right?)
//use the EL struts tags if not using JSP2.0 Container
<logic:iterate property="aVo.bVOlist" id="bVOitem"> <bean:write name="bVOitem" property="xAttr"/> <bean:write name="bVOitem" property="yAttr"/> </logic:iterate>
Obviously you would surround the above with table tags etc. Or you could
also use the display tag (search google or archives) that will do this for you.
